44.5.7 Register Access Protection
Registers with write access can be optionally write-protected by the Peripheral Access Controller (PAC), except for the following:
- Interrupt Flag register (INTFLAG)
- Status register (STATUS)
- Period and Period Buffer registers (PER, PERBUF)
- Compare/Capture and Compare/Capture Buffer registers (CCy, CCBUFy)
- Control Waveform register (WAVE)
- Pattern Generation Value and Pattern Generation Value Buffer registers (PATT, PATTBUF)
Note: Optional write protection is indicated by the "PAC Write Protection" property in
the register description.
When the CPU is halted in debug mode, write-protection is automatically disabled.
Write protection does not apply for accesses through an external debugger.
